发明名称 METHOD AND DEVICE FOR DETERMINING THE DUTY-CYCLES OF PWM CONTROL SIGNALS OF AN INVERTER
摘要 A method for determining duty-cycles of respective pulse width modulated (PWM), space vector modulated (SVM) control signals of an inverter, may include storing values of the duty-cycles as a function of a position of the multi-phase electric load in a look-up table. The method also may include determining a phasor angle representing applied sinusoidal voltages. The method also may include determining the duty-cycles as a function of the angle, and storing, in the look-up table, values of two pre-established waveforms relative to at least one duty-cycle as a function of the angle in at least two 60° degree angular sectors, by at least, identifying which of six 60° angular sectors the angle belongs, calculating a difference between the angle and an angular sector lower bound, and generating values as a function of the identified angular sector of the difference and the two pre-established waveforms stored in the look-up table.
